Last updated at 1300 Wednesday March 16th, Sydney time

We now have details on the temporary suspension of rebooking fees, and in some cases cancellation fees, to change a flight to Japan on Qantas, Jetstar, Air Canada, American Airlines, British Airways, Cathay Pacific, Delta, Emirates, Etihad, Finnair, Garuda, JAL, Singapore Airlines, Thai, Lufthansa, United-Continental and Virgin Atlantic.

Following the Japan earthquake and the closure of Tokyo's international Narita and Haneda airports, causing widespread cancellation of flights into and out of Japan, airlines are suspending the fees usually charged to change a flight or even cancel a ticket. This also applies to non-refundable tickets.

Narita Airport, which is Japan’s main international gateway, remains closed, although a spokeswoman for the airport said there was no visible damage to runways. Haneda Airport, which opened to international traffic late last year, has reopened several runways to resume flights.

However it's expected that flights to Japan will continue to be affected across the weekend and early into next week.

Australian Business Traveller has contacted all major airlines around the world flying to Narita and Haneda to confirm the details of their policy regarding changes to tickets, and will list them on this page as we receive details.
